Answer:
1) what's the eqn? x-2y=4?
then one soln could be (0,-2)
2) let the angle be x
x + 30°= 180°
x = 180° - 30°
x = 150°
3) Using law of exponents
(25)^1/3 × (5)^1/3
= (25×5)^1/3
= (125)^1/3
4) By exterior angle formula,
a + b = 120
since a and b are given to be equal
2x = 120
x = 60°
Hope this helps
